Some users can now use the dark Facebook on their mobile devices. This tool became available in some cases, as found by the site The Verge.
Dark mode is now available, a month ago, for the desktop version. It is now known that tests have started in the mobile version for selected profiles. It could soon reach the rest of the users, although there are no confirmations about it
It should be remembered that there are many other apps that already have dark mode, such as Instagram, WhatsApp and Messenger, all of which belong to Facebook. Twitter a also offers this alternative, both for iOS and Android operating systems.
One of the benefits of dark mode is that it saves on battery consumption. It should be noted that this saving is significant only in the case of OLED screens, becauses such displays are able to illuminate each pixel independently, but this does not happen with LCDs. In those cases, even if half of the screen is shown in black, those pixels are also illuminated and therefore not save as much battery.
Dark mode is now available in various apps, such as Instagram.
Is it beneficial for the eyesight?
Numerous studies have referred to the contrast between objects and the background and how having a light background and a dark attention object or focus improves readability. However this does not always seem to work the same for all users.
In the case of people with certain degenerative diseases, such as cataracts or macular degeneration, which has a decrease in contrast sensitivity, dark mode can make reading difficult.
On the other hand, in the case of users with good eye health the dark mode, which involves a decrease in the brightness of the display, can be beneficial to avoid visual fatigue.
Is the dark mode better for a good rest? There are visions found here. It is traditionally believed to be yes, but there is a recent study that questions this conclusion.
Dark mode reduces exposure to the phone's blue light. That's why this aspect is often seen as positive to improve the rest at night. A study by researchers at the New York Center for Light Research argues that artificial light causes the suppression of melatonin segregation, a hormone produced by the pineal gland and that controls the sleep cycle. In this sense, limiting exposure to artificial light, especially the blue light emitted by screens before going to sleep is beneficial.
However, a study conducted by researchers at the University of Manchester concludes that blue light seems not to be as harmful to our sleep patterns as it had been believed until now.
According to these specialists, the use of dim lights and cold shades at night, as well as resorting to warmer lights in the day can be more beneficial to our health. Experts reflect that the sunset is darker and bluer than daylight.
Beyond this, it should be noted that there is research that ensures that the use of electronic devices affect sleep intentionally that they are used in dark mode or not, because it is an equal light stimulus.
